00754W5 Outdoor temperature is constantly 14-15 degrees lower

00754W5 Outdoor temperature is constantly 14-15 degrees lower than the actual temp. I have reset the unit, placed the outdoor sensor in several locations still the same. Right now both the indoor unit and the outdoor sesnor are sitting on my desk. It says indoor temp is 73 while outdoor is 57 (sitting side by side). It has been this way since i bought the unit two months ago. Any ideas? If I ahve to replace a brand new sensor I will not be happy as it costs over half of what I paid for the whole thing.

Please try the troubleshooting steps listed below. Let us know if this corrects the issue. Thank you and have a great day!

Batteries: •Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) in sensor.•Quality brand batteries are recommended, including Duracell, Rayovac, Energizer, or Kirkland.•Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.•Heavy duty, extra strength or generic / store brand batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the way these types of batteries disperse power. Each battery should not exceed 1.6 volts.•Rechargeable batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the voltage instability of these types of batteries.•Mixing different battery types (brands, old/new, etc.) is not recommended.

Hard reset:- Bring both units side by side and remove all batteries, unplug display if it has an ac adapter- Change the ABC Switch to a different setting and ensure that both are on the same setting. example - If on A, move both to C- Place batteries into the outdoor sensor first - Place batteries into display- Allow units to sit side by side until they connect.
